1. Product Name
Allen Bradley 440T-MDALT10IIIJ Agricultural-Grade Safety Interlock SWITCH
2. Product Introduction
The Allen Bradley 440T-MDALT10IIIJ is an IP68-rated agricultural-grade safety interlock SWITCH, optimized for extreme wheat farm conditions—resisting deep water, fine grain dust, and strong pesticides for reliable safety control.
3. Product Description
The Allen Bradley 440T-MDALT10IIIJ is a heavy-duty safety interlock SWITCH, part of Allen Bradley’s 440T series engineered to tackle severe safety hazards in wheat agriculture and grain-handling operations. This Allen Bradley SWITCH focuses on extreme agri-environment resilience: its IP68 protection enables immersion in 1.5m of water for 30 minutes (critical for rainy-season wheat fields), blocks fine wheat grain dust (a major issue in silos and conveyor systems), and its chemical-resistant housing tolerates high-concentration pesticide residues from wheat crop treatments.
At its core, the Allen Bradley SWITCH features a fail-safe interlock mechanism: it stays locked until connected wheat equipment (e.g., automated harvesters, grain elevators, pesticide mixers) is fully de-energized, eliminating accidental contact risks during peak harvest or chemical handling. It integrates seamlessly with farm automation systems—compatible with 24V DC agricultural PLCs and grain moisture sensors—requiring no custom adapters to reduce on-site installation time. A high-visibility dual-color LED indicator (red = locked, green = unlocked) ensures clear status recognition in dim silos, bright outdoor fields, or rainy conditions, helping workers confirm safety at a glance.
Compliant with EN ISO 14119 (industrial safety) and ISO 23387 (grain handling standards), this Allen Bradley SWITCH meets Category 3 safety requirements with Performance Level d (PLd). It operates reliably in temperatures from -40°C to 90°C (adapting to frigid winter wheat storage and high-heat grain drying workshops), supports 10A current at 250V AC, and has a mechanical service life of 350,000 operations—ideal for frequent harvest cycles. Its compact size (8.8×6.4×2.5cm) allows flexible installation on tight spots like silo access panels and harvester guard rails.

5. Product Advantages

  • IP68 Extreme Protection: Resists 1.5m water immersion, fine grain dust, and strong pesticides—tailored for harsh wheat farms.

  • Wide Temperature Range: -40°C to 90°C adapts to winter storage and hot drying processes without performance loss.

  • Dual Standard Compliance: Meets EN ISO 14119 and ISO 23387, simplifying regulatory checks for grain facilities.

  • Farm System Compatibility: Works with 24V DC agricultural PLCs/sensors, cutting integration costs.

  • Long Durability: 350,000 mechanical cycles handle frequent harvest use, reducing replacements.

  • Clear Visibility: Dual-color LED ensures status recognition in rainy, dim, or bright agri-settings.

6. Business Insight on www.wheat-auto.com
While direct site access is unavailable, the “wheat-auto” domain confirms its focus on end-to-end wheat agricultural automation—serving commercial wheat farms, grain elevators, and food processors with solutions like automated harvesters, silo controls, and pesticide handling systems.
The Allen Bradley 440T-MDALT10IIIJ aligns with its core offerings: www.wheat-auto.com would integrate this SWITCH into high-risk, extreme-condition wheat equipment—rainy-season harvester guards (resisting water), pesticide mixer storage doors (tolerating chemicals), and flood-prone grain silos (withstanding immersion). It leverages the SWITCH’s ISO 23387 compliance to help clients meet food safety standards for processed wheat, critical for selling to manufacturers. Additionally, the business likely offers farm-specific after-sales support—such as water immersion maintenance guides and pesticide residue cleaning tips—addressing rural customers’ limited on-site tech resources. This ties to “smart agriculture” trends, using industrial-grade, extreme-environment switches to boost wheat efficiency while mitigating harsh farm hazards.
7. Application Scenarios
The Allen Bradley 440T-MDALT10IIIJ SWITCH excels in extreme wheat agri-environments:

  • Rainy-Season Wheat Harvesters: Mounted on engine guards, IP68 resists water immersion, unlocking only when the engine stops.

  • Flood-Prone Grain Silos: IP68 protects against water damage, ensuring safe access during post-flood grain retrieval.

  • High-Concentration Pesticide Storage: Chemical-resistant housing tolerates strong pesticides, securing hazardous storage areas.

  • High-Heat Grain Drying Workshops: 90°C resistance maintains safety control in hot drying processes.

  • Frigid Winter Wheat Storage: -40°C tolerance works for frozen silos, ensuring reliable interlock performance.

  • Outdoor Grain Conveyors (Rainy Regions): IP68 blocks rain and dust, keeping safety control consistent in wet weather.
